Why some people are survivalists and preppers and yet don't have a viable communications plan in place is beyond comprehension. However, some folks don't have such a plan in place because they either didn't realize they need one or because they don't know much about radio communications.
So enter in the soonway.net web site where we attempt to teach folks about radios, antennas, licensing issues, and more.
What you need is only an open mind about needing a communications plan and then rest is easy. This web site has many pages of information on it about radios and about radio antennas. All you need to do is identify what system may best fit your survival plan and then work the radios and antenna into your existing survival plan. There are a good many people who have a complete radio communications system in their bug out bag.
